How to “install” multiple Java versions?
How do you have multiple Java versions in Ubuntu 18.04 LTS?
In my Windows, I usually have 3 versions available for development. I do not have them installed in my system but rather, I can switch to different versions when I need to by pointing to the right jdk in Environment Variables. How can you do this in Ubuntu?

You should search the forum a bit more first. Look here askubuntu.com/q/740757/557184

Check available versions with some search like:
apt --names-only search "openjdk-.*jre$"
Switch between versions with:
sudo update-alternatives --config java
